IES: Illuminating Engineering Society of North America

IES, the Illuminating Engineering Society of North America, is a nonprofit organization that develops and publishes standards regarding lighting. Headquartered in New York City, United States, IES standards are in effect throughout all of North America with its nearly 8,000 members. Internationally, IES collaborates with the International Commission on Illumination to promote uniformity with the rest of the world. Standards from IES are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.

Below are IES's best-selling standards. To find additional standards, please use the search bar above.

ANSI/IES RP-8-25

Recommended Practice: Lighting Roadway and Parking Facilities

Intended Audience: Engineers, Designers, Manufacturers, Municipalities, End Users, DOTs, Architects, Utilities, Environmentalists, Regulatory Groups, Energy Groups, Rdwy Maint. Orgs, Electrical Contractors, General Public. Intended Interest Categories: Specifier (US), Affected (UA), Public Interest (UP), Academic, Research (GAR), Government, Regulatory (GGR), General SME (GSME), Organizational (OM). Description: This Recommended Practice is a compilation of lighting design techniques and criteria, all offered for quality roadway lighting solutions.

ANSI/IES RP-7-21

Recommended Practice: Lighting Industrial Facilities (Includes Errata 1)

The primary purpose of this standard is to serve as a guide and educational tool for the design of permanently installed lighting systems for industrial facilities. This Recommended Practice deals entirely with lighting and does not give advice on the construction of a facility. The scope of this practice covers the design of new indoor and outdoor lighting systems for new industrial facilities as well as the redesign of lighting systems in existing industrial facilities. Recommendations are based on quality lighting practices, including: the safe movement of vehicles and people, enhancing the productivity and comfort of employees, conserving energy, and minimizing maintenance. Recommended minimum maintained lighting levels and maximum uniformity ratio guidelines are provided but are subject to variation for special circumstances when based upon sound engineering judgment. (Includes errata.)

IES G-1-22

Guide for Security Lighting for People, Property, and Critical Infrastructure

This publication includes specific sections dealing with critical infrastructure and homeland security. In addition, its authors have incorporated throughout the document many of the lessons learned and applied by these agencies. This document is intended to provide specific guidelines for situations where it has been determined that security is an issue (refer to Section 2.1) and is an important determining factor in the design or retrofit of a given property.

ANSI/IES LM-79-24

Approved Method: Optical and Electrical Measurements of Solid-State Lighting Products

Procedures to be followed and precautions to be observed in performing reproducible accurate measurements of total luminous, radiant, or photon flux; electrical power; system efficacy; luminous, radiant, or photon intensity distribution; and color quantities and/or spectrum of solid-state lighting (SSL) products for illumination purposes, under standard conditions. Changes have been made in this new edition to update information and provide better guidance based on information gathered from proficiency testing associated with laboratory accreditation and independent research.

ANSI/IES RP-29-22

Recommended Practice: Lighting Hospital and Healthcare Facilities

The objective of this document is to provide context, define challenges, and identify recommended lighting design practices for healthcare-specific environments. This document is not prescriptive but is intended to provide guidance and to inspire by identifying possibilities that enable designers to develop the appropriate solutions for complex situations and spaces.

ANSI/IES RP-1-24

Recommended Practice: Lighting Office Spaces

Intended Audience: Lighting Practitioners, code officials, energy management organizations, building owners/managers, the general public. Intended Interest Categories: Specifier (US), Affected (UA), Public Interest (UP), Academic, Research (GAR), Government, Regulatory (GGR), General SME (GSME), Organizational (OM). Description: Lighting for offices and related areas. The 2024 edition includes updates on visual glare mitigation, Visual Displays, Prediction/Assessment and High Dynamic Range Imaging, updated control systems used in offices, and acoustic luminaires used in office spaces.

ANSI/IES TM-21-21

Technical Memorandum: Projecting Long-Term Luminous, Photon, and Radiant Flux Maintenance of LED Light Sources

This document provides recommendations for projecting flux maintenance of LED light sources using data obtained when testing them per ANSI/IES LM-80.

ANSI/IES LM-80-20

Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays, and Modules

LEDs typically exhibit very long operational life characteristics and, depending on drive current and use conditions, can be in use for 50,000 hours or longer.The light output from LEDs slowly decreases over time. This characteristic of declining output without sudden and permanent failure creates a risk that an LED-based lighting product near end of life may be operating but performing outside the product’s specification, or outside required codes, standard practices, or regulations. LEDs may also undergo gradual shifts in the emitted spectrum over time that may result in unacceptable appearance or color rendering, or degraded efficacy. This Approved Method describes the procedures by which LEDs are tested for luminous (or radiant, or photon) flux maintenance, and chromaticity maintenance or wavelength changes over time when operated under controlled environmental and operational conditions. The resulting measurements may be used for comparison of LEDs, and they may be utilized in models that project long-term changes in light output during the life of the LEDs.

ANSI/IES LM-63-19

Approved Method: IES Standard File Format for the Electronic Transfer of Photometric Data and Related Information

This document describes the standard data system and how to build a file using this system. The document addresses photometric data file formats specifically for data transfer, data storage and retrieval, and other data usage purposes.
